[PATCH 1/1] v4l: Bring back array_size parameter to v4l2_find_nearest_size

[Sakari Ailus <sakari.ailus@linux.intel.com>]

An older version of the driver patches were merged accidentally which
resulted in missing the array_size parameter that tells the length of the
array that contains the different supported sizes.

Bring it back to v4l2_find_nearest size and make the corresponding change
for the drivers using it as well.

Hi Mauro,

Here's the patch I mentioned. It restores the intended state of the
v4l2_find_nearest_size() API as it was reviewed and acked (by Hans).

This time the exact patch is tested for vivid.
